Notice how your CPU Score went from 60K+ to 20K+? That's PhysX for you... What happens is that if you leave PhysX enabled the two CPU Tests are going to get inflated because the GPU will take over the Physics part of the calculations instead of letting the CPU do the work.

Raising your core and your NB frequency will help quite a bit since your CPU score was lower than your GFX score. 4.3GHz+ should be doable with a few more volts. Remember, it doesn't have to be 24/7 stable to pass Vantage!
